Description
Primordial black holes (PBHs) serve as a compelling candidate for dark matter and a potential probe of early universe physics. One promising avenue for constraining their abundance is through the stochastic gravitational wave background (SGWB) induced by primordial curvature perturbations. In this talk, I will present how current and future gravitational wave observatories—including Pulsar Timing Arrays (PTA), Astrometry, and sapce-borne detectors—can set limits on the induced SGWB, thereby imposing indirect constraints on the formation and population of PBHs. I will discuss the sensitivity of these observations to different PBH mass ranges.
